Raman spectroscopy characterization of uranium hydride and deuteride

Raman spectroscopy has been used to characterize uranium hydride and deuteride. Raman shifts of UH3 and UD3 are evident to be inversely proportional to the square root of the mass of hydrogen isotope. The typical Raman peaks of UH3 and UD3 can be characterized by the mass difference of hydrogen isotope for one another. In addition, Raman peaks of uranium hydride and deuteride are identified to be at 725 and 938 cm−1 for UH3 and 518 and 669 cm−1 for UD3, respectively.
